Biscuits are dried & pressed to fit loosly in the slot, they expand with moisture and grip the slot from the inside. If your biscuits are fat its because they have been stored improperly and have picked up moisture. Put them on a cookie tray one layer thick and stick ‘em in a 250° oven for an hour or so.

All else fails, buy fresh.

Final possibility is your cutter is worn and the slots are narrow – easy to check.

This is a lesson on storage of biscuits, you want to keep them in a dry environment to avoid the swelling. I have an old unpowered freezer I store some other stuff in with a desiccant, that’s where my biscuits stay.
